Abstract

The ultrasonic-transducer mounting structure includes: a housing including: a body part which is formed into a hollow cylindrical shape and is provided at its front surface with a transmission surface allowing an ultrasonic wave to pass therethrough and is designed to accommodate an ultrasonic transducer therein; and plural connection pieces provided to a side surface of the body part; and a holder fixed to a rear surface of a bumper and designed to hold the housing such that the transmission surface of the housing is exposed via an opening of the bumper. The holder includes plural reception pieces to which the plural connection pieces are detachably coupled respectively. The plural reception pieces are fixed to the rear surface of the bumper to surround the opening.

Claims

1. An ultrasonic-transducer mounting structure comprising:

a housing including;

a body part which is fowled into a hollow cylindrical shape and is provided at its front surface with a transmission surface allowing an ultrasonic wave to pass therethrough and is designed to accommodate an ultrasonic transducer therein; and

plural connection pieces provided to a side surface of the body part; and

a holder fixed to a rear surface of a bumper and designed to hold the housing such that the transmission surface of the housing is exposed via an opening of the bumper,

wherein;

the holder includes plural reception pieces to which the plural connection pieces are detachably coupled respectively; and

the plural reception pieces are fixed to the rear surface of the bumper to surround the opening.

2. The ultrasonic-transducer mounting structure as set forth in claim 1, wherein:

the holder includes plural fixed plates respectively corresponding to the plural reception pieces;

each fixed plate has a first surface in a thickness direction and is fixed to the rear surface of the bumper at its first surface;

each fixed plate has a second surface in the thickness direction to which the corresponding reception piece is provided; and

each fixed plate is flexible to allow the fixed plate to be deformed along the rear surface of the bumper.

3. The ultrasonic-transducer mounting structure as set forth in claim 2, wherein

the fixed plate is provided with at least one of a slit and a groove to allow the fixed plate to be bent along the rear surface of the bumper.

4. The ultrasonic-transducer mounting structure as set forth in claim 1, wherein

the connection piece and the reception piece corresponding to this connection piece are designed to be in contact with each other in a rotation direction around a central axis of the opening.

5. The ultrasonic-transducer mounting structure as set forth in claim 1, wherein

the holder is designed to hold the housing such that the body part is in contact with the rear surface of the bumper at a predetermined pressure.
